PREPARATION AND SPECTROSCOPIC STUDIES OF COPPER(II), NICKEL(II), PALLADIUM(II) AND OXOVANADIUM(IV) CHELATES OF FLUORINATED SCHIFF-BASES

The copper(II), nickel(II) palladium(II) and oxovanadium(IV) chelates of two tetra-denate Schiff bases, N,N'-ethylene bis(1,1,1-trifluoro-6-methyl-2-oxoheptan-4-imine) (H2TF-IVA(2)en) and 1,2-propylenebis(1,1,1-trifluoro-6-methyl-2-oxoheptan-4-imine) (H(2)TFIVA(2)pn) have been prepared. The reagents and their metal chelates have been characterized using infrared, mass, H-1-NMR and UV/Vis spectrophotometry. The structures have been assigned to ligand and their metal chelates.
